The goal of this project is to create a functional satellite ground station, able to receive VHF transmissions from NOAA sats and more!

Pick the main satellite for observe #5

Closed fivitti closed 4 years ago

fivitti commented 4 years ago

I think that we should select one, main satellite to observe and prepare first version of our station for it. It will allow us to focus on the task and we will to have a clear goal.

This satellite should be high above horizon and fly often above Gdańsk. The best if this satellite transmit the graphical data (for example weather maps).

On the same frequency and similar orbit we should find two another satellites as backup.

I've implemented a solution that should address our needs. There's a new server set up at https://satnogs.klub.com.pl. There's PostgreSQL database and apache web server running on it. I've developed a script (tools/upload-obs.py) that uploads the resulting image and inserts appropriate entry in the database.

The website showing the results is simple, but functional. It dynamically loads the images from the database and presents in a table. The images can be inspected. This is rather basic, but should be enough for now.

I prepared the initial design scheme: schema Briefly - NOAA 18 sends meteo images, we receive them through an antenna that is connected to RPi using SDR. RPi is placed on the ETI roof near the antenna. We communicate with RPi from another computer via ssh.

What can we do with images?

My ideas:

I prefer reports.

Ok, but what's the goal of that report? Prove that we managed to do it?

We need to prove the usefulness of our system. Any other ideas for practical and simple use of the received images? I think that the report or very simple website will not take us too much time. Better ideas (such as analyzing these photos) are too time consuming.

+1 for simple website.

Considering that we chose the 137 MHz RHCP antenna we may officially assume that our main goal is receive the meteorogical images from weather sats. We may to specify (for prof. Moszynski) that we want to receive images from NOAA 18 (most often aboce Gdansk).

(See my analyse in #7)

Our long term goal is of course build the general purpose satellite communication station.
